Overview

CVE-2024-41053 is a medium-severity vulnerability affecting linux linux_kernel. It was published on July 29, 2024 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

scsi: ufs: core: Fix ufshcd_abort_one racing issue

When ufshcd_abort_one is racing with the completion ISR, the completed tag

of the request's mq_hctx pointer will be set to NULL by ISR. Return

success when request is completed by ISR because ufshcd_abort_one does not

need to do anything.

The racing flow is:

Thread A

ufshcd_err_handler step 1

...

ufshcd_abort_one

ufshcd_try_to_abort_task

ufshcd_cmd_inflight(true) step 3

ufshcd_mcq_req_to_hwq

blk_mq_unique_tag

rq->mq_hctx->queue_num step 5

Thread B

ufs_mtk_mcq_intr(cq complete ISR) step 2

scsi_done

...

__blk_mq_free_request

rq->mq_hctx = NULL; step 4

Below is KE back trace.

ufshcd_try_to_abort_task: cmd at tag 41 not pending in the device.

ufshcd_try_to_abort_task: cmd at tag=41 is cleared.

Aborting tag 41 / CDB 0x28 succeeded

Unable to handle kernel NULL pointer dereference at virtual address 0000000000000194
